IMPROVEMENT IN MACHINES FOR ROLLING HORSESHOE-BLANKS.

Specification forming part of Letters Patent N 0. 194,934, datedSeptember 4, 1877; application filed June 29, 1877.

To all whom it may concern Be it known that 1, JOHN H. SNYDER. ofRichmond, in the county of Henrico and in the State of Virginia, haveinvented certain new and useful Improvements in Machine for RollingHorseshoe-Blanks; and do hereby declare that the following is a full,clear, and exact description thereof, reference being bad to theaccompanying drawings, and to the letters of reference marked thereon,making a part of this specification.

The nature of my invention consists in the construction of horseshoebar-iron, and in a machine for rolling the same, as will be hereinaftermore fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, 1 will now proceed to describe itsconstruction and operation referring to the annexed drawing, in whichFigure 1 is a front elevation of my rollingmill. Figs. 2 and 3 aredetailed views of the rolls, and Fig. 4 represents the bar after it haspassed through the rolling-mill.

A A represent the frames or housings of the rolling-mill, in which areplaced three shafts, B B B geared together at one end by cog-wheels B B.The bottom shaft B has at its other end a miter-gear wheel, 0, meshingwith a similar wheel, G on a vertical shaft, 0, which carries upon itsupper end a roller, D. Directly opposite this roller is another roll,1), operating against the same, and this roll, D, may be rotated simplyby friction from the roll D, or the two rolls may be geared together inany suitable manner, if deemed more advantageous. The roll D has simplya circumferential groove, to, of uniform depth and width throughout, asshown in Fig. 3; while the roll D is formed with a circumferentialgroove of peculiar shape, the bottom of said groove being madeeccentric, forming four convex points, I), nearer the circumference, andthe intervening portions d being farther from the circumference. The barof iron G being passed and rolled between these rolls leaves one edgeperfectly straight, while the other edge forms alternate convexities hand concavities i, as shown in Fig. 4. Im-

mediately beyond the rolls D D are two ver- I tical rolls, L L,fastened, respectively, on the ends of the shafts B and B roll L isformed with a series of toothed flanges, m m, arranged in pairs, asshown in Fig. 2, and between each pair of these flanges a concavity, n,is formed in the roll. The iron The upper roll L is made perfectlysmooth, while the lower bar G passes immediately from the rolls D D f tothe rolls L L, and through the same, which i completes the blank,forming the creases f and indentations e for the nail-holes.

By this construction 1 form the bar in such a manner that it is thewidest at the points h,

which will form the toe of the shoe.

This is 5 of great importance, as the toe of the shoe is the part thatfirst wears out, or where the greatest wear comes; the bar being cut inthe 5 center of the concavities i, which part forms the heel of theshoe.

The bar is thus rolled by one operation, the edges first and then thetop and bottom, and by a proper formation of the rolls the bar may bemade part round or oval and part square, as may be desired, 1 or partflat and part square, or other various E forms.

out any fins at the edges.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In a machine for rolling horseshoe-blanks, the combination,substantially as described,

of the horizontal rolls D D and the vertical rolls L L, all arranged andconstructed substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this29th day of June, 1877.

JOHN H. SNYDER.
